PROTECTIVE COVER.

Application filed April '15, 1925.

This invention relates to improvements for use upon a Ford engine andwhich contemplates the provision of a tubular member which is arrangedtransversely within a pocket provided centrally of the engine 'lock andwhich is adapted to receive the usual and ordinary carburetter throttlerod thercthrough and yet prevent the access of dirt and the like fromentering the valve chests and better protect all parts of the engine asall dust, sand and extraneous matter which gets into the valve chest iswashed into the crank case by the oil supplied to the valves.

Another object is the provision of means arranged within an opening inthe cylinder block behind the elongated opening provided in the valvecover plate for completely enclosing the valve spring chamber in orderthat no cool air will seep or pass in and around the valve stems nordeposits of extraneous matter whereby the oil supplied to the valvestems from the crank case will in no way be contaminated or pollutedwhereby the correct lubricant may be applied to the valve springs andmechanism therefor and yet allow the heated air to favorably act uponsuch. mechanism to insure proper operation and easy starting the motorin general.

lVith the above and other objects in view, the invention furtherincludes the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawing and pointed out in the appended claims.

In the drawing 2- Figure 1 is a horizontal section taken through aportion of the engine block and showing the relative position of thetubular member therein.

Figure 2 is a front elevation of the valve chest protector plate.

Figure 3 is a detail perspective of a modified form of my tubularmember.

Figure 4 is an end elevation thereof.

Figure 5 is a vertical sectional view of the modification.

Referring to the drawing in detail, wherein like characters of referencedenote correspondnng parts, the reference character indicates a Fordengine block which includes a conventional form of opening or atransversely disposed socket 11 arranged between cylinders 2 and 3 ofthe engine and which is adapted to receive therein and Serial N0.23,408.

transversely thereof a carburettor throttle rod 12 which has itsopposite ends connected to the end of the steering column throttle rodand the butterfly valve arm on the carburetter.

This opening or socket furtherincludes a restricted entranceopening 13upon one end thereof as is well known in the usual and 14 that a spaceis left between the inner sides of the valve cover plates 15 and thecorresponding sides of the block 10 and in order to completely closethis space 1 pro.- vide a tubular member 17 which may befrustro-conicalin cross section and include an elongated end upon oneend thereof to register the correspondingly shaped opening providedcentrally of the valve cover'plate 15 and which has provided upon theelongated end of the tubular member 17 an outwardly extending plate orflange 18 which is riveted or otherwise secured to the inner side of thevalve cover plate 1.5 and in regise trat-ion with the opening 16provided there- The opposite end of this frustro-conical member 17 whichincludes outwardly and upwardly extending flange members 19. upon theouter sides thereof and which provide a pocket or the like in which isreceived a circular packing which is adapted to be forced against theinner side of the restricted entrance opening 13 within the opening orpocket 11 in order that drafts, dust and other extraneous matter will bepreventedfrom entering the valve chest 14 and be allowed only to passthrough the frustroconical member 17 As clearly illustrated in Figures3, 4 and 5 I have illustrated a modified form of my invention and whichincludes a frustro-conical member 17 having an outwardly and upwardlyextending annular flange 19 provided upon the smaller end thereof andwhich is adapted to receive a resilient packing or the like 20 as usedin the preferred form of my invention. The opposite end of thefrustro-conical member 17 includes an annular flange 18 provided thereonand which is correspondingly shaped with the elongated end and whichfurther includes a slitted portion 21 which extends outwardly from theinner sides thereof and which are adapted to be bent outwardly in themanner as clearly illustrated in Figure l and in so doing secure thisend of the lirustro-conical member 17 securely to the valve cover. plate15 as clearly illustrated, in Figure 5 of the drawing.

It will thus be noted from the foregoing description and accompanyingdrawings that this invention provides a very useful and advantageousattachment for use upon Ford motors and which will prevent theaccumulation ol? dust and other extraneous matter within the valve chestof the motor in order that the oil or the like contained therein willnot be polluted or in any way contaminated by the dust and otherextraneous matter which would materially intertore with the operation orthe valves in so far as it would make the valves stick and prevent theproper lubrication of the valve stems within their bushings, not shown,as well as prevent the accumulation of grit between the lower end of thevalve stems and the valve tappets in order that the valve heads will beproperly seated within their seats.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomake such changes as properly fall within the scope oi the appendedclaims.

Having thus described my invention what is claimed is 1. A-protectivecover for use upon internal combustion engines and the like comprising afrustro-conical member arranged within the transversely disposed openingprovided centrally of the engine block, means for securing one end ofthe conical member to a valve plate and means for resiliently supportingthe opposite end against the restricted entrance opening provided in thetransversely disposed opening.

2. A protective cover 01 the character described having an annularflange provided upon one end thereof, a circular pocket provided uponthe opposite end thereof, means for securing the annular flanged portionof the cover to a valve cover plate, and resilient packing meansarranged within the pocket provided in the opposite end of theprotective cover substantially as set forth.

A protective cover of the character describedhaving circular andelongated portions upon the opposite ends thereof, an annular flangeprovided upon the elongated end of the cover, a pocket provided upon theouter sides and adjacent the opposite end of the cover, a circularresilient packing arranged within the pocket and means included upon theannular flanged portion for securing the opposite end to the inner sideof a valve cover plate for holding the same in registration with acorrespondingly shaped opening provided centrally therein.

a. A frustro-conical shaped protective cover of the character describedhaving an upwardly and outwardly extending annular flange portionprovided adjacent the smaller end of the cover and providing a pockettherebetween, the opposite end of the cover being substantiallyelongated and including an annular flange upon the outer ends thereoi,and a plurality of slitted resilient members extending on the outer endsof the elongated ends and adapted to extend through a correspondinglyshaped opening provided centrally within the valve cover plate and bentthereon for rigidly securing this end of the frustro-conical protectivecover thereon.

In testimony whereof I aflix my signature.

JAMES BRYANT ROlVE.
